用Trefftz型边界解法分析了中厚板弯曲问题，发现了一类新的、因Trefftz函数溢机引起的"自锁现象"，并提出了一种消除这类自锁问题的"变量减缩法"．

Presented the Trefftz-type boundary solution method for analysis of the moderately thick plate bending problems. A new type of "locking phenomenon" which is caused by the overflow of Trefftz function has been observed and a so-called variable reducing procedure for eliminating such a locking problem is proposed.
